Creating a regex to get multiple values and print

I'm looking for any help with the code below. Basically the ip:port string keeps changing and may contain more than one true value in str and i wonder if is possible to use a regex using the search function to get the all ip:port and print in demo.


<p id="demo"></p>

<script>
var str = "Please 127.0.0.1:80 locate where 127.0.0.2:80 occurs!";
var pos = str.search("b(?:(?:25(0-5)|2(0-4)(0-9)|(01)?(0-9)(0-9)?).){3}(?:25(0-5)|2(0-4)(0-9)|(01)?(0-9)(0-9)?):d{1,5}b");...
